Sadowski was born in Chicago, Illinois, the son of Marirose and Robert Sadowski.[2] His mother is of Italian descent.

In 1994, at age 14, Sadowski met a young man who was getting back from a 2,000-mile road journey with his best friend and dared him to pull a longtime prank on his best friend when they got home. The man pretended to be in a catatonic state at a mental institution for the next twenty years, with his best friend coming to visit him every week for those years, only to find out it was a prank. Sadowski hasn't been charged for this alleged prank nor does the man's best friend know that Sadowski made him do it.[3]
